SHADE-ROLLER.

Specification of Letters Patent.

llatented Apr. 1, 1913.

Application filed July 16, 1912. $eria1 No. 709,624.

To all whom it may concern Be it known that 1, ALBIN OLsoN, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Shade- Rollers, of which the following is a specification, reference being bad to the accompanying drawings.

My invention relates to improvements in shade rollers and has for its object, among other things, the construction of a device that will combine within. itself simplicity of parts, and will be positive in its operation, and will also be constructed of as few parts as possible, and so designed as to be readily assembled and manufactured easily and at slight cost.

Referring now to the drawings, in which like numerals of reference designate similar parts throughout the several figures-Figure 1 is a front elevation of my improved shade roller with the shade itself omitted; Fig. 2 is an enlarged longitudinal sectional view of one end of my roller; Fig. 3 is a cross sectional detail view, the view being taken on the line 33 of Fig. 2 looking in the direction of the arrow and shows the locking and releasing cams, the roller tube being omitted from the figure; Fig. 4 is a similar view, the section being taken on the line 4-4 in Fig. 2, looking in the direction of the arrow; Fig. 5 is also a like view, the section being taken on the line 5-5 shown in Fig. 2 looking in the direction of the arrow and shows the usual latch mechanism; Fig. 6 is a similar view taken on the line 6-6 of Fig. 2, looking in the direction of the arrow, and shows the shade locking bar and a portion of the shade; Fig. 7 is a vertical sectional view taken on the line 77 in Fig. 8 and shows the manner of securing the shade locking bar in position; Fig. 8 is an enlarged longitudinal sectional view showing the location and construction of the parts making up one end of the shade roller; Fig. 9 is an end view looking from the right in Fig. 8, showing the removable shade standards, said standards being shown as about to be moved into their supports; Fig. 10 is an enlarged central sectional view of the roller tube, the shade locking bars being shown in elevation and said tube be ing broken away; Fig. 11 is a plan view of the parts shown in Fig. 10.

Tn carrying out my invention 1 provlde the usual roller tube 1 having therein a longitudinally disposed channel 2 which pro ects into thecylindrical surface of the tube and constitutes a key to hold securely the removable end members of the shade roller proper from rotating. It also serves to lock within the tube the shade itself. In the channel 2 ar located two locking bars 3 and 4 which are pivotally secured to the brackets 6 at 5. The bars 3 and 4t serve to secure the shade to the tube as indicated at 7 in Fig. 6 in the channel 2 which constitutes a part of the tube. The free end of each of the bars 3 and 4- is provided with a nose-piece 8 which enables the bars to be locked down in horizontal position and also serves to hold in position the removable end members 9 and 10 located at the ends of the tube 1.

The end members 9 and 10 each consist of a tubular member 11, shown in Figs. 2 and 17 ar constructed so as to provide a shoul-' der 18 upon each cam, which shoulders overlap the inside surface of the hub 13. The earns 16 and 17, when secured to the plate 15 by means of the screws 15, retain the H said plate 15 upon the hub 13, but permit of the rotation thereof for the purpose-of locking or unlocking the bars 3 and 1 as well as to secure the end members upon the respective ends of the tube 1. The bars 3 and 4 are locked down into horizontal position by means of the cam 16 and the tip 19 on the nose-piece 8. The cam 17 will force the bars 3 and 4t upwardly when the plates 15 are rotated in the direction of the arrow 20 shown in Fig. 7. To permit the bars 3 and 41 to be raised as shown by the dotted lines 21 in Fig. 10 the tube 1 is cut away at 22 shownin Fig. 11. By means of the channel 2 which passes through the slots 23 in the hubs 12 and 14, the tubular member 11 is held against rotating, but the plates 15 nevertheless can be rotated.

The shade roller proper is rotatably supported by two standards 24 located at either end of the roller, to which are pivot-ally secured arms 25 carried by blocks 26, slidably fitted within the bore 27 of the tubular member 11. Each block 26 is provided with a square rod 28 which fits slidably within a square shaped opening in the block 29 which in turn is rotatably mounted at 30 in the hub 12 as shown in Fig. 8, the block 29 being retained in position in said hub 12 by a collar 31. Thus far the construction of both end members 9 and 10 upon the ends of the shade roller are similar. To cause the roller with its shade to re-wind, a usual coil-' and the block 29 may be separated without entirely removing the set screw 36. The opposite end of the sleeve 35 is rotatably supported on a projecting pin 38 carried by the hub 33 as shown in Fig. 2.

In order that the spring may act, the

usual gravity pawls 39 are provided to 00- operate with the spring, which pawls fit into recesses 40 cut in the block 29. The pawls 39 are carried by the hub 12 as shown in Fig. 8. The blocks 26 act as a trunnion around which the tube 1 can rotate while the square rod 28 in turn keeps the block 29 from rotating while it likewise holds the sleeve 35. Therefore, according to my device, when the roller is rotated all the elements combined therewith, excepting the sleeve 35, rod 28 and block 26, will rotate, at which time the spring 32 will be tight ened or wound up. Each standard 24 is provided with a slotted base-block 39 which is removably retained by a bracket 40 adapted to fit the slots on the block 39. Hence it will be seen that the standards may be slid onto the brackets, thereby eliminating the use of screws for the purpose of securing the standards in position upon the windowframe or other support. As the standards are pivotally secured to the arms 25 as at 41, as shown in Fig. 8, such standards may be positioned as shown by the full lines in Fig. 8 or as shown by the dotted lines, as convenience may require, since the block 26 and the rod 28 may be moved longitudinally within the tubular member 11. A pin 42 is provided to prevent the block 26 and the rod 28 from passing entirely from within the tubular member 11. It will be seen therefore that the standard 24 may bemovedv time the ends of the rods 3 and 4 can be depressed, causing the nose-piece 8 to enter into the space 43. Now when the plates are rotated toward the left, the cam 16 will engage the projecting point 19 on the nosepiece 8 as shown in Fig. 7 and hold rigidly in position the locking bars 3 and 4.

There are many minor changes and alterations that may be made within my invention, aside from those herein shown and described and I do not wish to limit myself to the exactconstruction, but claim all that falls fairly within the spirit and scope of my invention.

What I claim as new and desire to secure by Letters Patent is the following, viz

1. A shade roller comprising a tubular body portion, a series of non-rotatable hubs within the tubular body portion, shade-locking plates at either end of the tubular body portion, a winding control mechanism inclosed within said end plates and the tubular body portion, blocks slidably mounted within the winding control mechanism, a sleeve rigidly secured to a block rotatably mounted within one of said hubs, support ing arms the inner end of one of said arms being connected, and rotatable in unison with the block secured to said sleeve, and a coil spring having one end secured to the inner non-rotatable hub and the other end to said sleeve, substantially as described.

2. A shade roller comprising a tubular body portion, tubular winding control members comprising a series of non-rotatable hubs slidably mounted within the tubular body portion, shade-locking plates at either end of the tubular body portion and containing within themselves a series of blocks slidably mounted within the inner tubular members and provided with a winding control mechanism, a sleeve rigidly secured to a block rotatably mounted within one of said hubs, supporting arms the inner ends of one of said arms being connected, and rotatable in unison with the block secured to said sleeve, and a coil spring having one end secured to the inner non-rotatable hub and mounted Within one of said hubs, supporting arms the inner end of one of said arms being a square shaped rod inclosed within and connected, and rotatable in unison with the block secured to said sleeve, and a coil spring having one end secured to the inne1 non-rotatable hub and the other end to said sleeve, substantially as described.
